Integrate Nano Defender with uBlock Origin to block Anti-Adblocker

A fairly common reaction to counter the rising use of adblockers is to implement anti-adblocking scripts to get Internet users to disable the content blocker on websites that rely on advertising revenue.

Update: Nano Adblocker and Defender ownership changed hand (except for the Firefox version), and the new version should be uninstalled immediately. We removed links to all versions except the Firefox version as a consequence.

Depending on how these scripts work, they may just display warnings when users visit the site with enabled adblockers or require that users deactivate the adblocker or whitelist the site to continue.

It is a race between creators of adblockers and anti-adblockers that does not address the bigger underlying picture in regards to advertisement on the Internet.

One option that uBlock Origin users have is to use Nano Defender's anti-adblocking capabilities. Nano Defender is an anti-adblock defuser by the creator of Nano Adblocker.

The process is a bit complicated for uBlock Origin, but it works without having to install Nano Adblocker in the browser of choice.

Integration in uBlock Origin

You find the instructions on GitHub, but here is everything explained in detail:

  1. Install Nano Defender in Chrome or Firefox.
  2. Enable the Adblock Warning Removal List in uBlock Origin. It is a list that is already available in uBlock Origin but not enabled by default. Click here to do so.
  3. Subscribe to the Nano Defender Integration filter list. The list is not already available, but you can subscribe to it with a click as well.
  4. The next step requires that you make a configuration change in uBlock Origin's configuration. You need to add a custom resource list in the advanced settings.
    1. Open the Settings of uBlock Origin.
    2. Check the "I am an advanced user".
    3. Click on the settings icon next to it that appears when you activate the option.
    4. Locate the variable userResourcesLocation and replace the initial value "unset" with
    5. Click on "apply changes"
    6. Close the tab.
  5. Subscribe to the Nano Filters list with a click on this link.
  6. Subscribe to the Nano Filters Whitelist list with a click on this link.


Most anti-adblocking scripts should be blocked automatically once you have changed the configuration of uBlock Origin and integrated the custom filter lists in the extension.

A quick test on several sites that use anti-adblocking functionality confirmed that this worked just fine at that point in time. The sites would load without the adblocking notification that they display normally when using adblocking extensions.

The lists get updated automatically and everything should work without you having to do anything form that point onward.

It is possible that you may run into connection issues with some sites that use anti-adblockers. It is still possible then to disable uBlock Origin, or, report the issue to have it addressed by the extension developer.

Now You: What is your take on sites using anti-adblockers that notify or block users with adblockers?

      Well it is a bit difficulty to distinguish between domains and files for instance.

      I know a service made by google that is similar to Google bookmarks.

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.

    No surprises here. This is just the beginning really. I cannot see a valid reason as to why anyone would continue to use the platform anymore when there are enough alternatives fill that void.

    I’m not sure if there is a point in commenting given that comments seem to appear under random posts now, but I’ll try… this comment is for

    My temporary “solution”, if you can call it that, is to use a VPN (Mullvad in my case) to sign up for and access Reddit via a European connection. I’m doing that with pretty much everything now, at least until the rest of the world catches up with GDPR. I don’t think GDPR is a magical privacy solution but it’s at least a first step.
